Before running  POST, complete the following preliminary steps:
1. If a power-on password has been established, type the password and
press the  Enter key.  If the password is not known,  clear the password.
2. Run Computer Checkup .
3. Turn off the computer and its external devices. 
4. Disconnect any external devices that you do not want to test. Do not 
disconnect the printer if you want to test it or use it to log error 
messages.
IMPORTANT: If the problem only occurs when an external device is 
connected to the computer, the problem may be related to 
the external device or its cable. Verify this by running 
POST with and without the external device connected.
5. Install loopback plugs in the serial and parallel connectors if you w\
ould 
like to test these ports. 
6. Ensure the hard drive is installed in the computer. 
7. Ensure that the battery pack is inserted in the computer and the 
computer is connected to an external AC power source.

To run POST, complete the following steps:
Turn off the computer, then turn on the computer.
1.  
If POST does not detect any errors, the computer will not beep. This 
indicates successful completion of POST test. POST has run 
successfully and boots from the hard drive (or from a bootable 
diskette if one is installed in the diskette drive).2.  
If POST detects errors, the errors are indicated by screen and/or 
audible messages. Refer to Power-On Self-Test (POST) Codes in 
the tables for a list of POST codes and their relevant descriptions.3.  
NOTE: If the system is not functioning well enough to run 
POST, or if the display is not functioning well enough to 
show POST error messages, refer to the Troubleshooting 
tables.

Diagnostic error codes occur if the system recognizes a problem while 
running the Compaq Diagnostic program. These error codes help identify 
possibly defective subassemblies. 
The following tables list error codes, a description of the error condit\
ion, 
and the action required to resolve the error condition.
IMPORTANT: Retest the system after completing each step. If the 
problem has been resolved, do not proceed with the 
remaining steps.
